A DIR file is a movie or animation project created by Adobe Director, an application used to create multimedia games and eLearning courses. It contains a project, which includes resources, links to externally referenced files, scripting code, and the timeline, which determines how the movie is played back.
Director movies can only be opened with the Director version used to create the file or a newer version. Some Director movies may be opened in Adobe Shockwave Player.
NOTE: Adobe Director was formerly known as Macromedia Director, which was acquired by Adobe in 2005. Adobe Director was discontinued in 2017.
